So the incorrect option is C the current flowing through the circuit is 27 amps because the current is related to voltage and resistance by the formula I = R + V

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).

Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.

To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists.

E = I x R

So the incorrect option is C the current flowing through the circuit is 27 amps because the current is related to voltage and resistance by the formula I = R + V

Explanation:

Sir Isaac Newton's three laws of motion are manifested in nearly every activity of everyday life including traffic accidents. From flying birds to racing cars these laws of motion are everywhere. In fact, nearly 99% of all activity in our physical world is usually governed by these laws.

Newton's laws of motion are very important when engineers design airplanes sports equipment cars train toys and more. This article describes Newton's three laws of motion in car accidents. Newton's first law of motion states that when an object is in motion, it will move at the same speed and in the same direction, or if it is at rest, it will continue to move until acted upon by an external force. In other words, objects have a natural tendency to continue doing what they were doing until they respond.

In the absence of an external force, a moving object maintains its original state of motion or remains stationary.  This law is usually called the law of inertia. Newton's second law of motion states that an object subjected to a force experiences an acceleration such that the force is equal to the mass times the acceleration. Mathematically this is expressed as . In other words, the force exerted during a collision is proportional to the mass of the colliding vehicle. This means that the more force a car collides with the more force it applies which means more destruction. The opposite is also true If the mass of the colliding vehicle is less, less force will be applied and there will generally be less destruction.

The magnitude of the induced current in the coil is 2.5298 A.

The induced current in the coil can be calculated using Faraday's law of electromagnetic induction,

It states that the magnitude of the induced electromotive force (EMF) is proportional to the rate of change of magnetic flux through a surface enclosed by a conductor.

The formula for the induced EMF is given by:

EMF = -N dΦ/dt

where N is the number of turns in the coil, Φ is the magnetic flux through the coil, and dΦ/dt is the rate of change of magnetic flux.

The negative sign indicates that the induced EMF opposes the change in magnetic flux.

The magnetic flux through the coil can be calculated using the formula:

Φ = BA

where B is the magnetic field strength, and A is the area of the surface enclosed by the coil.

Since the coil is circular, the area can be calculated as \(A = \pi r^2\), where r is the radius of the coil.

Using these equations, we can calculate the induced EMF and the induced current as follows:

Area of the coil, \(A = \pi r^2 = \pi (0.33 m)^2 = 0.345 m^2\)

Initial magnetic flux, \(\Phi $_1 = BA_1 = (2.90 T)(0.345 m^2) = 1.00065 Wb\)

Final magnetic flux, \(\Phi $_2 = BA_2 = (0.150 T)(0.345 m^2) = 0.05175 Wb\)

Rate of change of magnetic flux, dΦ/dt = \((\Phi $_2 - \Phi $_1)/t\)= (-0.9489 Wb)/2.30 s = -0.41296 W/s

Induced EMF, EMF = -N dΦ/dt = -(46)(-0.41296 W/s) = 18.9736 V

Induced current, I = EMF/R = 18.9736 V/7.50 Ω = 2.5298 A

Therefore, the magnitude of the induced current in the coil is 2.5298 A.

Answer:

1. m  = 40 kg

2. m = 0.55 kg

3. Because of the different values of acceleration due to gravity, g, on the planet and the earth.

Explanation:

1. GPE = 12000 J

h = 30 meters

g = 10 m/\(s^{2}\)

But,

GPE = mgh

where: m is the mass, g is the acceleration due to gravity, and h is the height.

12000 = m x 10 x 30

12000  = 300 m

m = \(\frac{12000}{300}\)

   = 40 kg

The mass of the diver is 40 kg.

2. GPE = 63.25 J

h = 11.5 meters

g = 10 m/\(s^{2}\)

GPE = mgh

63.25 = m x 10 x 11.5

63.25 = 115 m

m = \(\frac{63.25}{115}\)

   = 0.55 kg

The mass of the ball is 0.55 kg.

3. The pole vaulter's GPE on the earth would not be the same as that on another planet due to the variation in the value of the acceleration due to gravity on the two planets, even if he cover the same height.

Given that: m = 60 kg, h = 25 m, determine the GPE on the earth that has g = 10 m/\(s^{2}\), and another planet with g = 6.5 m/

Thus, on the earth;

GPE = mgh

       = 60 x 10 x 25

       = 15000

GPE = 15000 J

On the planet;

GPE = mgh

       = 60 x 6.5 x 25

       = 9750

GPE = 9750 J

Answer:

0.404

Explanation:

The calculation of confidence interval for the mean is shown below:-

Data provided in the question

Mean = 5.5

The Standard deviation for three values  is 0.7

Since there is 95% of the confidence interval so the critical value is

\(t_{0.025.5} = 4.303\\\)

Now

Margin error is

\(t_{0.025.5} = 4.303\times \frac{s}{\sqrt{n} }\)

\(= 4.303\times \frac{0.7}{\sqrt{3} }\)

= 1.74

Now,

The Standard error is

\(= \frac{s}{\sqrt{n} }\)

\(= \frac{0.7}{\sqrt{3} }\)

= 0.404

Hence, the confidence interval for the mean based is 0.404

When expressed as a fraction of more than 1, 18/4 is equivalent to 4 and 1/2.

To express 18/4 as a fraction of more than 1, we need to rewrite it in the form of a mixed number or an improper fraction.

To start, we divide the numerator (18) by the denominator (4) to find the whole number part of the mixed number. 18 divided by 4 equals 4 with a remainder of 2. So the whole number part is 4.

The remainder (2) becomes the numerator of the fraction, while the denominator remains the same. Thus, the fraction part is 2/4.

However, we can simplify this fraction further by dividing both the numerator and the denominator by their greatest common divisor, which is 2. Dividing 2 by 2 equals 1, and dividing 4 by 2 equals 2. Therefore, the simplified fraction is 1/2.

Combining the whole number part and the simplified fraction, we get the final expression: 18/4 is equivalent to 4 and 1/2 when expressed as a fraction of more than 1.

Explanation:

Answer:

A. 2 m/\(s^{2}\)

Explanation:

Mass of wagon = 15 kg

Horizontal force = 45 N

frictional force = 15 N

It is good to note that part of the exerted horizontal force would be used to overcome the frictional force on the wagon.

So that, total force exerted on the wagon can be determined by;

total force = horizontal force - frictional force

                 = 45 - 15

                 = 30 N

From Newton's second law of motion, we have;

F = ma

Where: F is the force applied on an object, m is its mass, and a is the acceleration of the object.

Thus,

30 = 15 x a

a = \(\frac{30}{15}\)

  = 2 m/\(s^{2}\)

The acceleration of the wagon is 2 m/\(s^{2}\).

Answer:

(i) It will take longer (75/22 times) the time to boil a given quantity of water compared to when the current is working at its rated capacity

(ii) The reasons are;

(1) For economy; most of the appliances in the home only require low power circuitry with thinner wire while a separate high power circuitry is created directly from the main supply for the high electric power rated appliances

(2) For safety; to prevent the over heating of the electric circuits when an high electric power appliance needs to be connected an high power electric power outlet has to be specified

Explanation:

(i) The power rating of the kettle = 3 kW

The voltage rating of the circuit, V = 220 V

The current rating, I = 4 A

The formula for electric power = I² × R = I × V

Therefore, we have;

Power produced = 220 V × 4 A = 880 V·A = 800 W

Hence, since the power produced is below the power rating of the electric kettle, it will take a longer time to boil a given amount of water than specified by the kettle manufacturer

The energy supplied H = V×I×t

Where:

t = Time in seconds

Therefore, we have;

3 kW = 3000 W;

3000 × t₁ = 880 × t₂

t₂/t₁ =3000/880 = 75/22

Hence the kettle will take 75/22 multiplied by the time it takes when working at rating capacity to boil a given quantity of water

(ii) This is so because the power consumption already factored in the electrical installation as well as the type of appliances utilized in the home allow for several low power rating consumption and few high power rating consumption

Therefore, for both economy and safety the electrical circuit are split to allow for the use of very thick copper or aluminium electric cables in the high power rating electric circuits to which can be plugged high electric power consuming devices such as the water heater and electric cooker

The low electric power consuming devices, such as the electric bulb and fans are connected to the low or "regular" power rating electric circuit outlets

The current required for high power and low power appliances is different and also the fuse rating required for both the appliances different, so two separate circuits are used for high power and low power appliances.

Three forces and each of magnitude 70 n all act on an object, then the magnitude of the resultant force acting on the object is 140 N.

To find the magnitude of the resultant force, we need to add the three forces vectorially. Using the parallelogram law of vector addition, we can draw a parallelogram with the three forces as adjacent sides. The diagonal of the parallelogram represents the resultant force.
Since all three forces have the same magnitude of 70 N, we can draw the parallelogram as a rhombus with equal diagonals. To find the length of the diagonal, we can use the Pythagorean theorem.
Let's call the diagonal (resultant force) F. Then, the two diagonals of the rhombus are equal to 70 N (since all sides have the same length). The angle between the two diagonals is 120 degrees (since the three forces are equally spaced around the object).
Using the law of cosines, we can solve for F:
F^2 = 70^2 + 70^2 - 2(70)(70)(cos 120)
F^2 = 4900 + 4900 + 2(4900)(0.5)
F^2 = 19600
F = sqrt(19600)
F = 140 N

The term "point of buoyancy" refers to the precise weight balance between a submarine and the water being displaced. The buoyant force of a partially submerged body, according to the Archimedes principle.

Is the same weight as the liquid that was displaced. As a result, the buoyant force is dependent on both the body's submerged volume and the fluid's density. The force that a fluid produces on an object that is partially or entirely submerged in it in an upward direction is referred to as buoyant force. Differences in hydrostatic pressure, or the pressure that a static fluid exerts, are what cause buoyancy.
